Description

The Sundown Audio Z-Series ZV6 18-inch subwoofer is designed for high-excursion, low-frequency performance. It features custom-tooled and patented frames, a quad-stacked 240mm (9.45”) diameter motor structure with a 100mm (3.94”) magnet stack height, and a hyper-extended pole for extreme clearances. The ZV6 utilizes a 3-inch diameter, 8-layer flat wire aluminum voice coil for increased motor force and output. Enhanced voice coil ventilation is provided by a high-velocity pole vent, heavily vented magnetic gap, and machined channels around the pole piece. This subwoofer is optimized for small-ported enclosures but can perform well in up to 50% larger enclosures for even deeper bass extension. Its linear suspension design aims for minimal distortion and maximum low-frequency output.
